An unexpected guest crashed a birthday party in Connecticut last weekend.

A large black bear showed up and helped itself to some cupcakes.

Laura Durst was having a party for her 2-year-old son when the grizzly creature popped up behind a guest and sniffed her.

She says she panicked.

Half of the adults grabbed the children and took them into the garage.

Some guests got into their cars and honked their horns while others continued yelling at the bear to scare it away.

However, the bear was unfazed as it made its way to the dessert table and began snacking.

Durst says they ended up waiting it out in the house.
